Abstract

The HZSM-5 zeolite catalyst was modified by an acidic ion exchange method to produce the Ga-HZSM-5 zeolite catalyst. The catalytic activity of HZSM-5 and Ga-HZSM-5 were studied at reaction temperature of 800Â°C and gas hourly space velocities (GHSV) of 7500 hrâ€“1. HZSM-5 and Ga-HZSM-5 catalysts were characterized by XRD, NMR, Nitrogen Adsorption and TPD. The characterization results revealed that aluminium was removed from the parent framework. Gallium loaded HZSM-5 is a better catalyst than HZSM-5 zeolite catalyst to produce liquid hydrocarbons.
